The upper portion of said I horn,

provided with a hollow shell to receive a a hollow tone- -.u;m connectedto sald hollow shellby a pin or lug formed on one of said members andentering a hole or opening in the other, a reproducer and telescopicconnections between said reproducer and said tone-arm. 2. In a talkingmachine, a bracket-arm secured to the casing of the machine and providedwith a hollow shell to receive the horn, a lug projecting from the innerWall of the shell adjacent to its lower end, a tapering tone-arm havingan aperture in its wall ad acent to one end and adapted to receive saidlug, an open-ended tube adapted to telescope with the contracted end ofsaid tapering tone-arm, a reproducel' and a flexible pipe connecting thesame to said tube.

3. In a talking machine, a bracket-arm secured to the casing of themachine and provided with a hollow shell to receive a horn, a lugprojecting from the inner wall of the shell adjacent to its lower end, atone-arm having an aperture inits wall adjacent to its enlarged end andadapted to receive said lug, -thereby affording a universal jointbetween said tone-arm and said shell, an openended tube adapted to beremovably held within the contracted end of the tone-arm, a reproducerand flexible connections between the same and said tone-arm.

4:; A talking machine comprising a frame,

a mandrel on said frame, a record on said mandrel, a reproducercarriagemounted to move in a right-line parallel with the axis of said mandrel,a reproducer supported by said carriage with its stylus in contact withsaid record, a tubular extension projecting from said reproducer," afixed support, an

amplifying horn mounted at its small end uponsald support, and a hollowtone arm engagement with said tubular extension projecting from saidreproducer.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
